Apple has reportedly increased its vapor chamber orders as it prepares stronger cooling systems for future iPhones, including its first foldable model and the iPhone 18 Pro lineup. The larger order volume suggests Apple plans to use the technology across more premium devices rather than limiting it to a single model.
Leaker Fixed Focus Digital wrote on Weibo that Apple has significantly raised its total vapor chamber orders. The source believes Apple is preparing for higher cooling demands in the rumored foldable iPhone and the 20th-anniversary iPhone expected in 2027.

Apple prepares vapor chambers for more iPhones
Apple introduced vapor chamber cooling with the iPhone 17 Pro, helping the device spread heat more evenly during gaming, video recording, and other demanding tasks. The system uses a small amount of liquid that turns into vapor near hot components, moves toward cooler areas, and condenses before repeating the cycle.
The timing also matches reports about Apple’s 2026 production plans. Apple has reportedly asked suppliers to prepare around 10 million foldable iPhones, up from an earlier target of 7 million to 8 million units.
The company is also expected to produce roughly 70 million iPhone 18 Pro and iPhone 18 Pro Max units. These three models will likely need better thermal control because larger displays, powerful chips, and thinner designs can generate more heat.
Reports also suggest Apple has resolved earlier hinge and manufacturing-yield problems with the foldable iPhone. That progress gives suppliers more confidence as Apple works toward a possible September launch.
